Serial No. 857,071.

To all whom it may concern:

Be it known that I, LAWRENCE A. SUBERS, a citizen of the United States, and resident of East Cleveland, in the county of Guyahoga and State of Ohio, have invented certain new and useful Improvements in Machines for Constructing a Laminated Cohesive Interwound Fabric Band, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

The objects of the invention are to provide an automatically opera-ting machine for manufacturing a continuous fabric band formed preferably from members composed of groups of close lying parallel yarns or plications Ser. Nos. 587,629, 587 ,630, 587 ,631,

587,632, 587,633 for hose and other manufactured products. I

The automatic machine described com prises a forming tube about which the tubular band is constructed and mechanism for constructing the tubular fabric band continuous thereupon, preferably from groups of close lying parallel yarns or threads in conjunction with mechanism for injecting a stream of fluid rubber into the interior of the tubular band, collapsing the band and placing the same under pressure to cause the rubber to permeate all parts of the band.

The invention also includes adjustable guides for the groups of close lying parallel yarns or threads, means for adjusting the angle at which they are fed to the forming tube, a device for stretching, forming and coating the collapsed band, and a device for winding the collapsed band upon a spool.

The machine also includes devices for forming a multiple band of a predetermined number of layers, having an inner lining of any desired material, with additional de- Specification of Letters Patent.

vicesfor maintaining this multiple band in a cylindrical state if so desired.

The invention also further consists in the combination and arrangement of parts and construction of details as hereinafter described, shown in the accompanying drawlngs and specifically pointed out in the claims.

In the accompanying drawings Figure 1 is a side elevation of the entire machine; Fig. 2 is a plan view of the same; Fig. 2 is a side elevation of a device for applying an mner reinforcing member to the former for subsequently covering with the tubular band; Fig. 2 is an end elevation. thereof; Fig. 3 is a side elevation of a; portion of the machine, showing the former, rubber tank and first two reels; Fig. 4 is a similar view of the remainder of the machine with the exception of the winding mechanism; Fig. 4* is a transverse section of reel showing the manner of mounting the spool containing the group of close lying parallel yarns or threads, as it passes from the spool to the reel; Fig. 4 is an edge elevation of the thread guide and supporting arm therefor; Fig. 5 is a transverse section on line ww Fig. 2, showing one reel, the thread guides, the three point support for the reel and operating means therefor; Fig. 6 is a transverse section on line y- -y Fig. 2 showing the winding mechanism and means for distributing the band upon the spool; Fig. 7 is an end elevation thereof; Fig. 8 is a section on line 2z, Fig. 2 showing the flattening rolls and tension or stretching rolls for the band; Fig. 9 is a side elevation thereof; Fig. 10 is a side view of the delivery end of the forming tube; Fig. 11 is an end view of the same showing the flattened aperture which delivers the liquid rubber in ribbon form adapted to enter the cavity in the tubular band, which is also partially collapsed by the expanded edges of the flattened end of the former. Fig. 12 is alongitudinal section of an additional machine element showing a multiple layer band upon a stationary hollow'mandrel and means for applying an exterior coating and means for applying internal and external pressure to the fabric, to keep it expanded; Fig. 13 is an end .view

1 thereof.

In these views A is a hollow cylindrical trols the flow of rubber from the receptacle to the hollow former.

A is a piston resting upon the top of th rubber in the receptacle and A isa weight resting on a shoulder A upon a stem A projecting vertically from the piston A and adapted to apply acontinuous pressure to the piston, so as'to eject therubber through the hollow former and 'throughthe open end thereof.

The forming tube is. designed to stationary and the tubular band is thereon by means of reels B, B, B and B respectively, which rotate about the former. Upon each reel are mounted the spools 13*, B composed of close lyingparallel yarns or threads, and as shownthe spoolsrare four in number so as to form a two-ply laminated interwound tube of threads upon the former. Each alternate reel revolves in a diflerent direction so that the threads cross each other at an angle determined by the rate of speed of rotation of the reels and the speed with which the tubular band is pulled off from the former.

The groups of close lying parallel yarns or threads T are already shown in Fig. 4: and are composed of parallel uncoated twisted yarns or threads and passes over a guideB attached to an arm B upon the reel by means'of a belt or screw '13 upon the guide so that the angle of the guide relative to the former can be adjusted to be as nearly the desired angle of the yarns or threads wound thereonas can be obtained. This guide is provided with two guiding grooves or positions'for the remain yarns or threads B and B respectively.

Each spoolis tightly mounted upon a rod B whicl'i-passes through a bearing B and tension uponthe spool is obtained bymeans of an arm B pivoted upon a projecting end of the rod at B This arm is provided with a shoulder 13 at one end'engaged by a spring pressed pin B longitudinally secured in the rod, so asto pressthe outer end of the arm against the reel. A friction block 13 such as arguto wood provides the required friction. The arm also forms a locking device to retain the spool in position and when extended as shown in dotted lines,

permits the spool and rod to be withdrawn. Each reel is mounted upon two rollers B and B and is provided with toothededge at B- -engaged by a driving pinion B formed which rotates the reel and has flanges B, B which serve with the rollers B and. B to form a three-point support for the reel.

The reels are all operated from a common shaft C by means of the friction rolls C, C mounted thereon engaging the friction disks 7 C C upon the shafts C G which also carries the bevel pinions B 22 which in turn engage the bevelgears B B fixed to the shaft B and fixed to this shaft is also the spur pinions B 13 which engage the toothed periphery of the reels B B The friction rolls C, C are slidingly mounted upon the main shaft C upon splines C, C and are adjusted upon the face of the disk 0 C by means of arms C, C which are operatively connected with the friction rolls by means of pins or screws C, C operating in annular grooves C C therein, and screw shafts C C on which the arms C, C travel.

i The requisite pressure for the driving of the friction disk C by the friction roll 0 is obtained by the screw bushing C in the bracket (1 upon the shaft G engaging the thrust ball bearing C which in turn engages the shoulder C upon the shaft C thus pressing the friction disk C against the friction roll C.

In Figs. 8 and 9 are shown the pulling, stretching and flattening devices. Here the rollers D, D are shown between which the outer end of the tubular former is supported and which also assists in pulling and sliding 100 the fabric along the forming tube. These rollers are pivotally mounted upon arms D D pivoted respectively upon the end of the worm wheel shaft, D and the pin D secured to the standard D and are adjustable to regulate the pressure and provide for the use of mandrels of different sizes by means of the slotted extremities D D and screws or bolts D 1). These rollers are secured upon shaftsD, D and are rotated in opposite directions by means of pinions D D intermeshing gears D D upon shafts D", D and on the longer shaft D is also mounted a worm wheel D which is operated by means of a worm D upon the com- 11 mon actuating shaft C the speed being determinedby the relative proportions of the 1 gears. After passing between the rollers D, D the tubular fabric passes between the flattening 12 rollers D, D one of which D is provided with overlapping flanges D D while the other is spring pressed and the friction of these flattening rollers is a double'one, first to produce the band shape required and second to force the rubber or other adhesive material injected through the hollow former into the tube through the fabric and thus thoroughly saturate it with rubber from within outwardly.

The shape of the mouth D of the tube is such as to facilitate the flattening of the fabric before passing underneaththe flattening rollers. This is clearly shown in Figs.

10 and 11, and the shape is such as to expand the tubular fabric laterally while the fluid rubber is being injected therein.

At E, E are seen pulling rollers having a number of gradually tapering divisions over which the flattened band passes, thus exerting an increasing pressure on the band which slightly stretches the same and se cures a powerful grip. This upper pulling roller is operated by gears E E and E*. The gear E is on the shaft D.. From this pulling device the band passes to a spool or reel F in a winding device. This reel is mounted loosely upon a shaft F and is provided with a friction drive similar to the tension device described for the thread spools. Here F is an arm pivoted in the end of the shaft F a shoulder F5011 the arm engages the end of a spring pin F in the shaft and retains the arm which is pro: vided with a friction point F in engagement with the flange F of the reel.

The reel is operated by means of the worm wheel F engaging a worm F 8 upon the shaft F. A device operated by the reel is employed to lay the band evenly upon the reel and consists of a sleeve F having a flange F which is provided with a pin F engaging a hole in the other flange F of the reel, so that the sleeve will revolve with the reel. Upon this sleeve is a bevel pinion F which engages the bevel gear F on a shaft F On this shaft is an adjustable friction roll F which engages a friction disk F upon a shaft F having a cam F thereon.

The requisite driving pressure of the friction disk F against the roll F is obtained by means of the screw-bushing F on the shaft F pressing the thrust ball bearing F against the shoulder F of the shaft F". The cam F is provided with a groove F which engages a roll F upon the screw pin 13 in the arm F arranged to reciprocate upon a guide F this arm is provided with an adjustable band guide E which guides the band backward and forward over the reel as the arm F reciprocates upon the guide F It will be seen that the speed of the reel controls the speed of the sleeve and gear thereon, and the speed of the pulley will remain constant since if the gradually increasing diameter of the reel tends to affect the speed of reeling or winding the band the friction arm F will slip on the flange F of the reel F. I

The position of the friction roll F on the disk 1* controls the relative speed of the cam F to that of the reel F and therefore since one revolution of the cam F produces The other end of widths of bands may be closely wound on the reel.

In Figs. 2 and 2 are shown views of a device for inserting an inner lining of fabric or metal or other material in the tube in such a manner as to fit closely therein when it is flattened. Here H is the flexible strip to be inserted wound upon a spool H and pressed over the hollow former in advance of the construction of the fabric. H is a curved roller adapted to press the strip H upon the former. H is a supporting roller opposite the roller H and H* is a third roller having flanges H which engage the edges of the flexible strip H and prevent it from rotating. The roller H is eccentrlcally mounted at H to provide for adpistment of pressure. A standard H supports the several parts.

In Figs. 12 and 13 are shown an element Q of the machine to be used in connection with the same general construction of stationary hollow former and reels when an inner lining is employed. Here A is the former, A a lining, A and A are the several layers of the laminated interwound fabric, forming a tube as it appears before flattening. A, A, and A, A are pairs of feeding rollers operated from a common shaft A and intermediate worms and gears A and A. A

tank of rubber A or other adhesive material incloses the fabric to apply the outer coating thereto.

Compressed air or other internal pressure is applied to the fabric through openings A A in the forming tube and external pressure is applied to the fabric through a tube A and an annular chamber A inclosing the fabric. The fabric can afterward be flattened or left cylindrical as desired. 7
